I'm having issues with my monk chars, the interface doesn't seem to be workign proply with a monk, tried reseting and even if I create a fresh monk the UI doesn't install properly, all my other chars are fine though which is a little odd

I had the
"x has been blocked from an action only available to the Blizzard UI." issue for some time but after having a dig about the net I found that a addon called !NoTaint sorted it out, I'm now able to change my talents on demand :D
